Letters Patent No. 101,069, dated March 22, 1870 g autedated September 22, 1869.

IMPROVEMENT IN APPARATUS FOR MEASURING-.LIQUIDS The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ELI F. WILDER, of Lowell, in the county of' Middlesex and State of Massach nsetts, have invented new and useful Improvements in Oil-Gans; and I do hereby declare that the following is a full and exact description thereof,l reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement' and construction of the receiver or oil-can, whereby the user is enabled to accurately measure the oil drawn from the same, and at the same time, during the operation of drawing, the oil is completely filtered and cleansed from all particles of' dirt, dust, &c., and the interior ofthe can is kept perfectly clean.

'lo enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation.

Figure l represents a plan of my improved oil-can with the 4cover removed.

Figure 2 represents a side elevation of the same.

Figure 3 represents a vertical section showing the can complete and its working parts.

Similar letters in the different ligures indicate. corresponding parts.

a represents the can or receiver, which is made of the required common size Aand shape, its body being straight, and contracted at the top, and provided with a suitable flange which forms the neck a of the same.

The top of the can a is further provided with a filling inlet, b, and handles l1 b for carrying or moving the saine.

Connecting with and fitting in the neck o is the tuneled gatherer c, provided with top and bottom flanges c and d.

lhe top flange c serves to hold the cover el and rack e.

The bottom flange d fitting in the neck o'receives the filter-cup e', its bottom being constructed of gauze and Ifilled `with a suitable filtering material, f.

Through the'bottom of' the gatherer c is a sutlicient number of' holes or ducts, as indicated by arrows in the drawings, for the escape of the waste or excess of'oil, and it is provided with a tube or bearing, f', which prevents thewaste oil from passing into the receiver a, except through the filter-cup c and serves also for a top bearing for the pump g. This pump is provided with a nose g', which has a suitable stop-cock, h. The top of the pump g is in form ot' a tunnel and its inside provided with a ligured gauge h', which accurately indicates and measurcsthe quantity of' oil required, at any given time drawn from the receiver a,

measurement being reckoned and started from the nose g' tothe top oi' the pump g. The top of the pump gis also provided with a cross-bar, which strengthens the same, and accommodates, by furnishing a bearing for the piston fi., which is supplied with a handle, t', at the top. At the bottom is a common pump-box, j, which iitsnicely and works in the interior ofthe pump g. The bottom of the pump is providedwitha stationary box, j', its valve k being furnished with a spring, k', which serves to keep the valve k closed when the pump-box j descends. Connected to the bottom, in the inside of the receiver or can a, is au annular flange, t, which is perforated with holes or conducting ducts This fiangc Z receiving the filter-cup m, the barrel of which being formed of two annular rings of wlre gauze m' on', between which is filled with filtering mal terial u, leaving a vacuum between thepump q and the inner gauze lining.

Operation.

The oil-can being thus constructed and its several parts adj ust-ed in their respective places, is then ready for use.

The can a being filled with oil, which may be done through the inlet b, or with greater facility by removing the pump g from the receiver or can a, and inserting it in the barrel containing the oil, and`attac ing a pipe or hose to the nose y' of the pump g, and connecting with the inlet b ot' the can a. In either case, when iilled and the pump g'being in position iu the can a, the operator, if required to fill a vessel without measurement, operates the pump g by aid of the handle t', drawing the pist-on z' upward in the usual way, alternately, unt-il the required quantity is drawn from the can a into the same.

' It an accurate measurement or a given quantity of oil is to be drawn the cock h is-closed, the pistou i is operated as before until the oil ris'es in the tunneled part of the pump g to the required given point or fig` ure ou the gauge h', which indicates the exact quantity of oil required. The cock h is then opened, and this quantity of oil is allowed to discharge through the nose g into its previously prepared vessel.

In both, or either case, the oil isconipelled to passI through the filtering-cup m before entering the pump g, thuscompletely purifying and cleansing the oil from all particles of dirt, impurities and set-thugs, which always are deposited outhe bottom of' ca'ns before'being discharged from the pump g, and also prevents much of the usual and ordinary wea-r ot' the boxes 7' and j', whilst in operation.

The escape and waste of oil, occasioned through carelessness or otherwise whilst drawing the oil from the pump g througlrthe nose g', is conveyed to the f ilter-cup e by aid of the gatherer/c, where it passes througlrthe ltering material f into the receiver or can g, thus eiectually filtering this excess and waste from all impurities before passing into the same, which may have collected on the vessellled.

'lhepumpl g, gatherer e, and lterers'e and m are so constructed as to be adapted and operated in the cans now in use, thus obviating the unnecessary expense of new receivers or cans.

rlhus, it will be seen by the use of my improved oilcan with its new arrangement and construction of devices, saves to the user the entire cost and space of a full set 'of measuring vessels, a perfect purifier from all particles of dirt, settlings, and sediment to oils, rendering them clean and purefthusr increasing the value of the same for illuminating or lubricating purposes, besides saving the constant usual waste and trouble attending the same.

What I claim as'my invention, and desire to secure by Letters Patent, is-

The filtrer-cups m and e' and gatherer c, in combinationl with the pump g, when arranged substantiallyas and for the purposes herein described.
